[email protected] Abstract: It is controversially discussed if and which interventions policymakers should implement to promote healthier, more sustainable, and more ethical food choices. Often, policy measures suffer from a lack of data. This is especially true for the growing field of online grocery shopping. Yet, it not always feasible to test the impact of each possible policy intervention in the field. Here, computer- simulated shopping experiments offer a complementary approach. Recent evidence suggests that they heighten the realism of consumer experiments and collect valid data at a relatively low cost. In this paper, we introduce an open-source toolset that offers multiple avenues to develop and run experiments in the context of online grocery shopping. Hence, it supports researchers and policy makers in evaluating instore-intervention aiming to support more sustainable food choices.
